What Are Tocopherols?

What Makes Gamma Tocopherols so Important?

Vitamin E activity doesn’t come from one single molecule, but from a family of related molecules called tocopherols and tocotrienols. There are four tocopherols (alpha, beta, gamma, and delta) and four tocotrienols (alpha, beta, gamma, and delta), of which only alpha-tocopherol was recognized in the 1960s, by the government, to have Vitamin E activity, which is measured in International Units (I.U.s).

Because of that decision only the alpha-tocopherol portion of a Vitamin E product is considered “Vitamin E,” so, the I.U. content of Vitamin E supplements generally refers to only alpha-tocopherol. But recent research shows that the whole family of Vitamin E isomers provides valuable health benefits. New findings about Gamma Tocopherols are especially intriguing.*

Each softgel of UNIQUE E® Mixed Tocopherols Concentrate contains a minimum of 300mg of d-gamma tocopherol.

Gamma Tocopherol is part of the Vitamin E family and has both antioxidant and non-antioxidant functions in the human body.

Recent research suggests that:

  • Gamma Tocopherol supports a healthy immune system response and normal cell growth.1,2*
  • Gamma Tocopherol is an antioxidant and supports balanced inflammation cycles both in vitro and in vivo.3*
  • Taking a Vitamin E supplement with only d-alpha tocopherol instead of the entire mixed tocopherols family of isomers can deplete the level of d-gamma tocopherol in the body.4*

Unlike other Vitamin E supplements that provide little to no d-gamma tocopherol, UNIQUE E® provides a powerful 300mg of d-gamma tocopherol in every softgel. While researchers and marketers alike have only recently recognized the importance of d-gamma tocopherol, our customers know that A.C. Grace Company has proclaimed the importance of d-gamma tocopherol since 1962! Vitamin E is a complex of molecules that work together synergistically. UNIQUE E® Mixed Tocopherols is a specialized proprietary formula of concentrated tocopherols specifically designed to provide the highest biological activity and maximum synergistic benefits of the all-natural complex.*

The NATURAL formula contained in UNIQUE E® is High in GAMMA and High in ALPHA content because we know the two isomers work closely together in the human body. Then we add a proprietary amount of each of the DELTA and BETA isomers to provide a full-complex of the four tocopherol isomers as they work synergistically together in the body, just as in nature.
